... We introduce a pressure-dependent rock physics model for shales and sands to analyze the effects of pore pressure and diagenesis on high-impedance reservoirs. With datasets at multiple scales (plugs, logs, and seismic) we show how diagenesis and composition combination impacts the seismic...

... Predrilling pore pressure prediction is of great importance in reservoir exploration. High-accuracy pressure prediction prevents drilling accidence and promotes the development of natural resources. Traditional modeling process using Eaton method has poor fitting performance under complex...

...” parameter for shale oil, because it related to the enrichment of hydrocarbon and can also be helpful to fracturing of the shale formation. The rock physics relation between BCD and seismic anisotropy is influence by both stress (confining stress and pore pressure) and shale intrinsic anisotropy...

... stress models are incorporated by utilizing well logs and other calibration data. Fluid injection and the creation of hydraulic fractures are simulated, and subsequent stress changes on nearby faults due to pore pressure and poroelastic stresses estimated. When slip is initiated on faults due...

With the use of Monte Carlo simulations (Xue et an iterative approach to estimate changes in the water al., 2019) or existing simulation grids (Dramsch, 2019), the saturation, gas saturation and pore pressure of the reservoir...

... In this paper, we have shown methodologies to remove the effect of TOC from compressional velocity data. The resultant TOC/kerogen-free V P can be used to optimize pore-pressure estimation in unconventional shales. reservoir geomechanics complex reservoir pore pressure reservoir...

In real rocks...

... the model with two different pore fluids. The composite sphere model is then used to estimate Brown-Korringa parameters for clay-rich rocks. The models are applied to a geomechanical problem: computing the change in pore pressure due to erosional uplift of low-permeabilityrocks. Presentation Date: Monday...

... such as borehole diameter, pressure in the borehole, weight on bit, revolutions per minute, and torque, they depend also on formation properties such as the geomechanical properties of the rock, pore pressure, and in situ stress. We describe a workflow for predicting such formation properties using the results...

... Velocity based pore pressure prediction has been successfully used to predict overpressure and underpressure zones to avoid drilling hazards. More recently overpressure estimation has been used in reservoir characterization to analyze productivity in a shale reservoir – “… overpressured shale...
